Mission accomplished! The car is new to me so still learning details but took about an hour replacing just the sensor without removing anything but the cabin filter cover and the tray underneath. Did not touch the abs block, master cylinder or plastic divider. Stuffed a bright colored rag underneath the sensor/hoses to catch anything and also helped viewing. Someone else mentioned it was like playing Operation, very true.

The dealer I purchased the car from last month replaced the front brake rotors and pads; sure enough the sensor was wet from brake fluid which apparently caused the failure and subsequent intermittent running of the pump. I wasn't getting any error codes.

There was residue vacuum in the hose (could hear it as I removed existing sensor) so the failure seems to be the senor itself, not the gasket.

Thank you!
